The following recommendations are based on our experience in growing plants for over 35 years, as well as recommendations recently acquired through industry research. The following soil mixtures should be incorporated throughout the area surrounding the root zone of plants. Our recommendation is to dig the hole at least 2 times the width and as deep as the depth of the root ball of the plant.
Group 1: Deciduous & Needled Evergreen Trees & Shrubs
Add to a wheelbarrow full of existing soil in the following ratio: 2 shovel fulls of peat to 1 shovel full of manure (or other substituted composted organic material).
* except those that need higher peat/organic content: use Group 2
Group 2: Broad-leaved Evergreens & Related Ericacae Plants (Azaleas, Hollies, Mt. Laurel, Blueberries, etc.)
Add to a wheelbarrow full of existing soil in the following ratio: 3-4 shovel fulls of peat to 1 shovel full of manure (or other substituted composted organic material of low pH).
